As society progresses, there is the need for land and stocks of capital to produce make possible the opulence of life which defines the bourgeois world. Within a hunting-gathering band, people can get by just with what they are able to secure for themselves with labor alone. Tools like axes and bows in wide use, but fitting the nomadic lifestyle of hunter-gatherers, these tools are personal items which can be kept on the person of their owners, and there is very little accumulation of tools actually going on.
With accumulation and the ownership of land comes the opportunity for kleptocracy in those societies. The necessity of there being lands and stocks of capital goods for which people are the residual claimants of opens human society to the exploitation of those claims for ill. Such manipulation can come in the form of the idle landowners being able to secure power for themselves within Parliament through the manipulation of rotten boroughs or the mafia extorting protection money from trifling shop owners. Both result in people who are contributing little to others being able to secure power and resources for their own benefit, and both would be impossible in a hunting-gathering society. The progress of society from the conditions of the hunting-gathering band therefore create the conditions in which corruption and kleptocracy can flourish largely because of the existence of settled lands, and valuable stocks of capital goods.
However, we should not proceed from that conclusion to a longing for the egalitarian hunting-gathering band. Kleptocratic elements are inevitable in any human society with any material advancement. As such, they should often be accepted simply as part of the costs of opulence and prosperity rather than as a plague which must be exterminated at any costs. Sometimes it is even refreshing when corruption is clearly corruption rather than as passed for something more pure. Take the Federal government, so many of its employees go on to work for private companies that are able to use the tacit knowledge those new employees have of the Federal government for their own profit. It’s corruption on a massive scale, and it is even more blameworthy because those responsible simply won’t be honest about what they’re doing, but continue to masquerade as benevolent officials.
